Designing and Validating Cuidador Web App for Self-Reported Pain among Children and Adolescents in Oncology Care

This study aimed to construct and validate a mobile application to guide children and adolescents in oncological care in self-reported pain. This is a descriptive study, based on a systematic instructional design that was conducted from 2022 to 2023 on working in pediatric care at two hospitals in Brazil. The content was validated by healthcare professionals, using the content validity index and cutoff score of 0.80. Face validity was assessed by children and adolescents, and a 90% agreement rate was used. The application, named "CuidaDor Web App," comprises four sections: user identification, presence of pain through numerical and facial scales and a body map, history of records, and informative materials. In the content evaluation, the judges assessed seven items: Language, Content, Illustrations, Layout, Motivation, Relevance, and Usability Assessment. The overall content validation index was 0.95. A face validation involved 24 children and adolescents, achieving over 90% concordance rate. However, usability requires parents' assistance for children using the tool. The CuidaDor Web App was developed and validated by healthcare professionals, children, and the target audience. The app may contribute to the management of pain in children and adolescents with cancer during hospitalization and at home. Future studies are needed to evaluate the age group that benefits most from technology and the use of the application as a tool for nurses and healthcare professionals.
